Asking users for solutions yields incremental ideas like "faster horses." Instead, ask them to tell detailed stories about their workflow. This narrative approach uncovers the true context, pain points, and decision journeys that direct questions miss, leading to breakthrough insights about the actual problem to be solved.

Founders instinctively view the world through a "supply lens," where their product is a central feature. This biases perception, making it impossible to see the pre-existing struggles (demand) that drive purchases. To see clearly, you must mentally remove your product and yourself from your view of the world.

Customers, like founders, have a gap between their stated beliefs and actual behaviors. Instead of relying on discovery interviews, watch them work. Observing their actions reveals their true operating philosophy—what they genuinely value—which is a more reliable guide for product development than what they say.

Customers describe an idealized version of their world in interviews. To understand their true problems and workflows, you must be physically present. This uncovers the crucial gap between their perception and day-to-day reality.

Operating with a "supply lens" creates a fantasy where customers, upon seeing your product, will magically alter their path to adopt it. The harsh reality is that if people aren't already struggling, your product is an irrelevant distraction. You're effectively shouting at passersby who are content on their journey and have no reason to listen.

The only reliable way to understand a customer is to "forward deploy"—work alongside them in their actual environment. This direct experience of their job closes the context gap that interviews can't bridge, revealing unspoken needs and frustrations.

To truly understand B2B customer pain points, data and interviews are insufficient. Product teams must immerse themselves in the customer's environment, such as by working for an advertiser for a week or shadowing an accountant for a day, to gain firsthand workflow experience and develop deep empathy.

When customers use your product in surprising ways, don't just build features for the new use case. Apply the "demand lens" by rewinding time. Investigate what struggle or "pull" existed in their world *before* they discovered your product to understand the core, pre-existing demand that is driving their behavior.

The first and most critical mindset shift for selling is to completely ignore your own product or service. Instead, focus exclusively on the customer's situation: what they are trying to do, what options they've considered, and why they are stuck. Thinking about your product biases your understanding of their reality.
